A vise can do more

Excellent Frank S! The simple projection engages corner of part; a vast improvement. Great use of mechanics/ physics to rectify an issue. Mine will 'spit' off steeper angles, without some material to increase friction. Mechanical engagement beats coincidental friction every time.
Just used it to machine 'horns' of press stand I hinted at, still not quite ready to post. I sectioned rectangular tubing for a tapered profile for clearance, welded top and bottom back together.
Also reporting on spectacular occurrence during the bandsaw sectioning process. Amazing amount of tension in that tube, spread open like petals when sawn across sides diagonally. Of course, demonstrates residual force, stored energy, from rolling process used to form tubing from flat sheet.


Proves again what is going on in 'our' off topic thread. Experience is priceless. Those who discount it, haven't invested their time to learn; so the value isn't appreciated.
